VISE.

Specification of Letters Patent. P t t d June 20, 191

Application filed May 28, 1912. Serial No. 700,252.

To 0Z6 w/wm it may concern Be it known that I, GEORGE R. SHARP, a citizen of the United States, residing at Larned, in the county of Pawnee and State of Kansas, have invented new and useful Improvements in Vises, of'which the following is a specification.

An object of the invention is to provide a vise for securely clamping and securing articles or bodies.

The invention embodies, among other features, a frame for rigid engagement with a solid body or bench, the said frame embodying a stationary jaw and having'a movable jaw adjustably mounted thereon with auxiliary jaw members for removable engagement with the said stationaryjaw and said movable jaw, the mentioned stationary jaw and said movable jaw being employed in connection with heavy and large work that is to be securely clamped in rigid position, whereas the said auxiliary jaws are adapted to be mounted upon the stationary and movable jaws and are particularly adapted for use in clampingsmall work in rigid and stationary position. y

In the further disclosure of the invention reference is to be had to the accompanying drawings constituting a part of this specification in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure 1 is a side elevation of the vise; Fig. 2 is a plan view; Fig. 3 is a vertlcal longitudinal sectional view taken on the line 3-3 in Fig. 2; Fig. 4 is a vertical transverse sectional view taken on the line 4-4 in Fig. 1; and Fig. 5 is a perspective view of one of the auxiliary clamping jaws.

Referring more particularly to the views, I employ a frame 10 including a base 11 having beveled sides 12 terminating at their apex, in a flange 13 constituting a track 14, a head 15 being integrally formed and cast with the base 11 at one end thereof, and a stationary jaw 16 being cast with the frame 10 at the other end thereof, the track 14 being formed between the head 15 and the stationary jaw 16. A horizontally extending screw rod 17 is journaled on the head 15 and stationary jaw 16, the outer end of the said rod extending beyond the stationary jaw and terminating in a squared portion 18, on which is rigidly mounted a suitable handle 19, a collar 20 being mounted to encircle the screw rod 17 adjacent the inner withdrawn or disengaged from the station-' ary jaw 16.

A jaw 22 is mounted to slide on the track 14, the said jaw having a recess 23 formed in the under side thereof to receive the flange 13, the mentioned under side of the jaw 22 being inclined to operate over the beveled portion of the base 11, the said jaw 22 being provided with a threaded opening 24, through which is passed the screw rod 17 so that when the handle 19 is operated the jaw 20 will be moved toward or from the stationary jaw 16.

The jaws 16 and 22 are each provided with a clamping flange 25 and recesses 26 are provided in the upper sides of the jaws 16 and 22, the said recesses having a convexed wall arranged in one plane and a concaved wall arranged in another plane, said wall being adapted to constitute seats to receive auxiliary jaws 27 and 28 having similarly shaped walls, the mentioned auxiliary clamping jaws being provided with recesses 29 in which the clamping flanges 25 of the jaws 16 and 22 are adapted to extend, suitable retaining flanges 30 being formed on the auxiliary jaws 27 and 28 and adapted to extendbeneath the clamping flanges 25 to secure the auxiliary jaws 27 and 28 in rigid position upon the stationary jaws 16 and 22 when an article is arranged between the auxiliary jaws and the screw rod oprated to securely clamp the article therebetween.

It will be readily seen by referring to the views that the jaws 16, and 22 are employed in connection with heavy work or material in order to securely clamp the same therebetween, the auxiliary jaws 27 and 28 being employed for rigidly clamping smaller work or material, it being readily apparent that the auxiliary jaws can be removed at any time from engagement with the jaws 16 and 22 when it is desired to employ only the larger jaws 16 and 22.

My device is particularly adapted for use in connection with a carpenters bench and a series of apertures 31'are preferably pro vided in the base 11, suitable bOlts or screws 1 being passed therethrough for the purpose r rlilgidly securing the device up n the enc It will be understood that I do not limit myself to the construction disclosed in the drawings nor to the particular manner of securing my device to a bench or the like, and that various departures may be made without departing from the spirit of the invention, the scope of the invention being definedin the appended claim.

Having thus described my invention, I claim:

A jaw construction for Vises comprising a pair of main jaws each; formed with a laterally extending fiange of a lengthequal to the width 01; the jaw anda recess in its upper surface, said recess having a concave Wall arranged in one plane and a convex Wall and flanges 01": all of said jaws being so arranged as to allow said auxiliary jaws to swing toward each other;

In testimony whereof I afiix my signature in presence of two witnesses.

GEORGE E. SHARP.
